Looks great for a stylized fantsy/sf statue. It's tall, but not oddly so for a statue (appx 11 ft at 1/100) and should be able to provide a bit of functional cover/concealment. As to finish, hit it with a metal or all surface primer (I like Duplicolor sandable) and you can paint it to look like whatever you want. White primer with a wash of grey or tan would get close to those pictures.

One thing I have had a bit of issue with using similar adornments is clipping the ring. Try to clip as close as you can, but be ready to use a micro metal/diamond file to get the nub down. If you are lucky, it will be a cheap solder job on the ring that you can wiggle loose (the solder connection being cheap soft metal) and then just trim and sand!
